[0008] Preferably, an overflow groove is provided on the top surface of the packaging frame, and the top surface of the anti-fall-off block and the bottom surface of the overflow groove wall are in the same horizontal plane.

The ventilation pipe is a copper pipe, and the heat of the coolant is conducted through the copper pipe, and the heat of the ventilation pipe is dispersed through the ventilation groove, which facilitates the heat dissipation of the coolant, thereby reducing the temperature of the liquid cooling plate, facilitating the heat dissipation of the substrate and the LED chip body, reducing the operating temperature of the LED lamp beads, extending their service life, improving working stability, promoting natural convection and radiation of heat, and improving the overall heat dissipation efficiency.

[0021] 3. Insert the plug of the sealing cover into the slot of the packaging frame, and the outer wall of the semicircular block abuts against the wall of the overflow groove. At this time, the bottom surface of the sealing cover abuts against the top surface of the packaging frame, and the sealing cover is fixed by the elastic clamp and the card slot. After the fixation is completed, the LED chip body and the packaging glue are protected by the transparent convex mirror and the sealing cover to prevent the invasion of external impurities and moisture. During use, the heat of the packaging frame is transferred to the sealing cover, and the sealing cover is dissipated by the heat dissipation copper sheet, which reduces the failure rate caused by high temperature or external factors, reduces the influence of temperature on the LED chip body and packaging glue, and reduces the occurrence of packaging glue being damaged or falling off due to high temperature, thereby ensuring the stability and reliability of the LED lamp beads and facilitating the use of the packaged LED lamp beads.
